Grill the Beef. Heat your grill to medium-high heat. Remove steak from marinade and add it to lightly oiled grates. Grill it for 5 minutes, then flip and grill another 5 minutes.
What is London Broil?
London Broil is a cut of beef that is marinated, then cooked (usually grilled or broiled), then sliced and served. The name refers to the cooking method, not the cut of meat. In fact, you can use different cuts of beef to make London broil. Top Round steak is the most popular. It is cut from the rear and has a lot of flavor, but it typically needs tenderizing before cooking. The marinade makes it tender and juicy. Flank steak is another popular cut. Try it with skirt steak or other leaner cuts of beef that will benefit from a good marinade. It’s all about the marinade. See my London Broil Marinade recipe for more discussion. Let’s talk about how we make grilled London broil, shall we? Next, score the London broil with a cross hatch pattern to allow the marinade to really get in there and flavor the meat. Marinate the meat either in a shallow dish or in a large plastic bag. Be sure to cover the meat as much as possible. Cover and refrigerate overnight for. I recommend at least 6 hours for a marinade, but 24 hours is better, so try to get it going the night before, or in the morning. Got any questions? Ask away! I’m happy to help.

I like to use my ThermoPop meat thermometer from ThermoWorks (I"m an affiliate). Works great! Remove from heat and let it rest 10 minutes to allow the juices within to redistribute. Finally, slice it against the grain and serve it up! So good! I hope you enjoy it!
Spicing Things Up
The chili peppers add a lot of flavor and heat. I used a jalapeno pepper, habanero pepper, and a couple of vibrant red Fresno peppers. Try it with a ghost pepper. Ghost peppers have an excellent heat, over 1 Million Scoville Heat Units, and they’re quite fruity, as are habaneros, which have a very respectable heat level as well. If you’re serious about your heat, include more ghost peppers, or go with something even hotter, like scorpions, 7-Pots, or the Carolina Reaper. If you’d like to tamp down the heat and not go TOO crazy, consider red cayenne peppers or ripened red serranos You’ll still get a pleasant level of heat without going overboard.
